sbin/mountd mountd.c
Log:
Fix a long-standing bug relating to the handling of SIGHUP: mountd
would call malloc, stdio and other library functions from the signal
handler which is not safe due to reentrancy problems.
Instead, add a simple handler that just sets a flag, and call the
more complex function from main() when necessary. Unfortunately to
be able to check this flag, we must expand the svc_run() call, but
the RPC library makes that relatively easy to do.
